The source describes avoiding platform download warnings as a reason for this installation path. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** The downloaded app can launch without the quarantine-based warning or block that would otherwise apply on macOS. - **Evidence paths:** package.json, install.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:53:18.477Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install.js downloads a release archive, checks its SHA-256 against the packaged manifest, extracts it, then removes the macOS quarantine attribute. - **Rationale:** The automatic installer deliberately bypasses macOS quarantine protections for a downloaded executable, which is a real security risk. The release is package-aligned and checksum-checked, so the inspected source does not establish malicious payload behavior or justify blocking publication. - **Files touched:** vendor/ - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs install.js automatically after installation., install.js says the installer uses npm to avoid SmartScreen and Gatekeeper download warnings., On macOS, install.js removes the quarantine attribute from the downloaded app., The manifest pins the app release to the Francois GitHub repository and release tag. - **Evidence against:** The installer checks the downloaded archive against a SHA-256 value from the package manifest before extracting it., The downloaded app and desktop integration are presented as the package’s stated purpose. ## Affected versions and remediation This report applies to francois@0.36.0. - Review the evidence and your use of francois@0.36.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
